본 고안은 농용 트랙터의 주 변속기에 관한 것으로서, 특히 2개의 축과 3종류의 기어를 적절히 조합하여 종래와 같이 4속을 얻을 수 있도록 함으로써 주 변속기의 내부 구성을 간단히 하고 제작 원가를 절감하며 용이하게 분해 조립할 수 있어 정비성을 향상시킬 수 있도록 한 것이다.The present invention relates to the main transmission of the agricultural tractor, in particular, by combining the two shafts and three types of gears to achieve a four-speed as in the prior art to simplify the internal configuration of the main transmission, reduce the production cost and easily It can be disassembled and assembled to improve maintenance.

잘알려진 바와 같이 농용 트랙터에 있어서의 트랜스 미션은 트랙터의 주행은 물론 PTD 출력을 변속 전달하는 것으로서 주 변속기와 부 변속기가 전후로 결합 구성되어 주변속기에서의 4속 부 변속기에서의 3속 변속으로 정합 전, 후진 12속의 변속이 이루어지도록 되어 있는데, 이와 같은 농용 트랙터의 트랜스 미션에 있어서의 주 변속기를 구성함에 있어서 종래에는 다수의 축들과 상호 변환 치합되면서 엔진의 회전수를 변속시켜 주는 각부의 기어들을 변속 조건에 따라 각기 다른 다양한 규격 및 크기를 갖는 기어들로 조합하였는바 트랜스 미션의 제작시 다양한 규격 및 크기를 갖는 기어들을 제작하여 조합하여야 하기 때문에 그 구성이 매우 복잡해지고 제작비용 상승과 생산성이 극히 저하되며, 트랜스 미션의 고장 수리를 위한 분해 조립시 그 규격 및 크기가 복잡 다양하여 각 단의 기어가 혼동됨으로써 작업이 매우 난해함은 물론 부품 관리가 어렵다는 문제점을 내포하고 있었다.As is well known, a transmission in a farm tractor transmits the PTD output as well as the driving of the tractor. In order to configure the main transmission in the transmission of the agricultural tractor, the gears of each part which shifts the engine speed while shifting and interlocking with a plurality of shafts are shifted. Combination of gears with different specifications and sizes according to the conditions. Since the gears with different specifications and sizes must be manufactured and combined during the manufacture of the transmission, the composition becomes very complicated, and the manufacturing cost increases and productivity is extremely low. Standard for disassembly and assembly for troubleshooting of transmission And due to the complexity of the various gears of each stage confusing the work is very difficult as well as containing the problem of difficult parts management.

따라서 본 고안은 상기의 종래 제반 문제점을 해결하기 위한 수단으로 3종류의 기어와 2축을 조합하여 구성된 농용 트랙터의 주 변속기를 제공함으로써 주 변속기의 내부 구성을 간단히 하고 기어 종류를 줄여 생산성을 높히고 부품 관리를 용이하게 함은 물론 정비성을 향상시킬 수 있게 한 것이다.Therefore, the present invention provides a main transmission of a farm tractor configured by combining three types of gears and two shafts as a means for solving the above-mentioned conventional problems, thereby simplifying the internal configuration of the main transmission, increasing the productivity by reducing the type of gear, and managing parts. In addition to facilitating easy to improve the maintainability.
